Correct syntax for disabling a radio button after it was chosen

Question

is it possible to disable a radio button? after a user chooses one of the radio buttons , i don't want them changing answers so i want to disable the radio button, i've used

radioButton.setEnable(false)

but still it's able to choose other radio buttons.

What is the correct syntax in disabling a radio button after it was chosen?

 JRadioButton b1 = new JRadioButton("");

   public void actionPerformed(ActionEvent e) {
     if ("disable".equals(e.getActionCommand())) {
